An antenna is a device used to transmit and receive signals. Antennas are the key components of any wireless communication system. They can convert a voltage signal into electromagnetic waves and vice versa. The transmitting and receiving functionalities of the antenna are characterized by Maxwell’s equations.

Due to rapid development and growth in the wireless communication industry, computational techniques were introduced for creating low cost virtual antenna designs. This innovation made the process of designing highly efficient antennas easy and cost effective.

In today’s life, we are surrounded by different systems using different antennas operating at different wavelengths. It is very important to protect health from excessive radiation and prevent the interference of various emitting devices operating in a common electromagnetic environment, to ensure the correct operation of the different systems. With Altair Feko it is possible to design an antenna and to examine the characteristics of its electromagnetic waves.

Students and engineers can design an antenna using Altair Feko, analyse the impact of electromagnetic radiation at the transmitter and receiver modules and their impact on the environment. Feko has an easy to use interface which enriches the user experience. Feko could solve EM problems which helps students/engineers to enhance their knowledge in the field of electromagnetics and in their projects/research.

Altair Feko is a comprehensive computational electromagnetics (CEM) software used widely in telecommunications, automobile, aerospace, defence industries and Academia/Research. Feko comprises of distinguished multiple frequency and time domain EM solvers. Hybridization of these methods enables the efficient analysis of a broad range of EM problems, including antennas analysis, antenna placement, windscreen antennas, microstrip circuits, waveguide structures, EMC analysis, radomes, electromagnetic interference (EMI), Bio-electromagnetics, radar cross section (RSS), periodic structures and RFID.

Some of the benefits of Feko are One Product, Multiple Solvers, True Hybridization, Solver Accuracy and Performance, Optimization, Model and Domain Decomposition, Non-Radiating Networks.

Feko Components and Workflow

View the typical workflow when working with the FEKO component – CADFEKO POSTFEKO.

CADFEKO

Create or modify the geometry (or model mesh) in CADFEKO. Apply solution settings, define the frequency, specify the required sources and request calculations. Mesh the model to obtain a discretized representation of the geometry or model mesh. Validate the model using the CEM validate tool to ensure the model is correct. If any warnings or errors are given, correct the model before running the FEKO solver.

Feko solver

Run the FEKO solver to calculate the specified output requests.

POSTFEKO

Create a new graph or 3D view and add the results of the requested calculations on a graph or 3D view. Results from graphs can be exported to data files or images for reporting or external post-processing. Reports can be created that export all the images to a single document or a custom report can be created by configuring a report template.

After viewing the results, it is often required to modify the model again in CADFEKO and then repeat the process until the design is complete.
